MATHEMATICAL MODEL OF ROLLING STOCK OSCILLATIONS ON A CURVED TRACK SECTION FOR AN ON-BOARD DECISION SUPPORT SYSTEM

Abstract

From the point of view of the effect that oscillations have on the train movement, the most influential is the process of passing a curved section of the track by the rolling stock. The article deals with the problems associated with dynamic processes during the movement of railway transport along curved sections of track. In particular, the paper analyses the wagging and lateral overrun oscillations, which have a significant impact on traffic safety, passenger comfort and the degree of wear of mechanical components. As a way to mitigate the problem of oscillations, the paper considers supplementing the decision support system with a new software component. As a result of the analysis of modern scientific research, a mathematical model of diesel train movement has been developed that takes into account the peculiarities of passing curved sections of the track. The model allows for the analysis of dynamic characteristics and can be used as a software component in decision support systems for onboard control systems of railway transport in Ukraine. It has been determined that the passage of a curved section of track at high speed significantly affects the safety of further traffic. In this regard, the identification of the critical speed is an urgent task and is the direction of further research.
